The Quiz League of London (QLL) is a British quiz league based in London. Founded in 1990 as the Quiz League of South London, it was southern England's first independent self-administered quiz league. The matches themselves are mostly hosted at pubs or social clubs.
The QLL has since incorporated many teams from the Greater London area and currently (2016–17) has three divisions of ten teams each. The QLL runs the annual London Open Quiz Festival, which features a knockout competition between other quiz leagues from up and down the country and an annual open buzzer quiz using the University Challenge format. The QLL also runs a President's Cup league competition aimed at the top players, a Summer Friendly League designed to be a bit less challenging, a knockout Cup and Plate competition, the Brain of London (an individual competition using the MIMIR format), a charity night and a summer social. Players in the QLL include previous Mastermind, Brain of Britain and Only Connect winners and other television and radio quiz winners. The only founder member club of the original four teams extant in the QLL is the Accies (original name being Jimmy Hill Club).
Two teams, one , one play each other, responding orally to a questionmaster.
The QLL format consists of 64 questions in 8 rounds of 8 questions each asked to individuals on the teams alternately. Correctly answering your own question scores 2 points though it can be passed within the team (if the player chooses not to answer) or over to the other team (if the player or team answer wrongly) for one point.
In the QLL format, there is no conferring as such. Where a player decides not to answer their question, the team captain will normally decide which other member of the team is to answer by assessing the hand signals made by the players on the team and his/her own judgement. The opposition will also use hand signals to decide who is to answer the question in the event of it being passed over. After 4 rounds, the order of answering changes so the team who began round 1 going first begin round 5 going second. This is done by switching each team's questions from A to B or from B to A depending on which questions they started with.
